Sanitation infrastructure that keeps pace with your project.
Every day a commercial job site operates without adequate restroom access is a day that runs below capacity. It's not a compliance footnote — OSHA requires portable sanitation at construction sites based on crew size, and the cost of noncompliance isn't just a fine. It's project delays, crew dissatisfaction, and the kind of friction that compounds across a multi-week build.
The companies that handle this well don't treat sanitation as an afterthought. They spec it in from day one, the same way they spec power access and material staging. That's the operating logic behind every commercial rental we run at Porta Potty Rentals FMB. When you work with us, you're not calling in a portable toilet. You're setting up a service relationship that runs for the life of your project.
Here's what happens when that relationship is built correctly — and what it costs when it isn't.
High-traffic units built for sustained daily use. Reinforced tank capacity, heavy-duty door hardware, and a servicing schedule calibrated to your crew count. Available in multi-week and month-to-month rental periods with scale pricing for multi-unit orders.
Best suited for: general contractors, civil construction crews, infrastructure projects, and any commercial site with consistent daily workforce access requirements.
For larger commercial sites — those running over twenty workers, client-facing job walks, or public-adjacent builds — portable restroom trailers provide the capacity and appearance that standard units can't. Multiple stalls, running water, interior lighting, and a fixed footprint that accommodates high traffic without service interruptions.
Commercial compliance means ADA compliance. Our ADA-accessible units meet federal specifications: wider door clearance, interior grab bars, and ground-level threshold. Required on most permitted commercial sites. We advise on ratio requirements for your crew size so your compliance posture is correct from project start.
A unit without reliable servicing is a liability, not an asset. Our commercial service programs are built around your project schedule — weekly service as a minimum, with higher-frequency options for large crews. Each service includes full waste extraction, tank treatment, interior cleaning, and supply restock. A service record is maintained for your files.
For projects running three months or longer, we offer priority response agreements: any service or mechanical issue gets a same-business-day response, including unit swaps if needed. No escalation required — it's built into the agreement.
We run on confirmed schedules, not approximate windows.
Every service visit has a confirmed date on your project calendar. If something changes on our end, you're notified before the window passes — not after.
We know OSHA portable sanitation ratios.
For any commercial job site in Knox, PA, we'll calculate the required number of units for your crew size and provide documentation to support your site inspection file. You won't have to research it.
Multi-site coordination is part of the offering.
For contractors managing multiple active sites, we run a single point-of-contact model: one account manager, consolidated billing, synchronized service schedules. The operational overhead doesn't scale with your project count.
We've handled emergency replacements on active builds.
A unit that goes out of service during a project doesn't get a next-available-slot response from us. Active commercial clients get same-business-day response as a standard expectation, not an escalation request.
A general contractor in Knox, PA started a commercial build with a crew of twelve. Six weeks in, the project scope expanded and the crew grew to thirty. The single unit originally ordered was no longer adequate. We received a call on a Thursday and had two additional units on-site by Friday morning. No contract renegotiation. No delay to the following week. Just an adjusted rental that matched the new reality.
A site manager was two weeks from a city inspection and realized their portable sanitation setup wasn't ADA-compliant for the number of workers on record. We replaced the existing unit with a compliant configuration within 48 hours and provided written documentation of the unit specifications. The inspection passed without a sanitation note.
A civil contractor running an eight-month utility project needed servicing they could forget about — something running on autopilot while they focused on the build. We set up a bi-weekly service program with automated confirmation emails after each visit. For the entire project, the site manager received exactly zero service-related complaints from the crew.
You provide crew count, project duration, and site access details. We confirm unit count, placement logistics, and the servicing schedule that fits your timeline. You receive a written scope confirmation before delivery.
Units arrive within the agreed delivery window. Placement is confirmed with whoever is on-site. ADA positioning and service access clearance are verified before the driver leaves.
Service visits run on the confirmed schedule. After each visit, a brief service confirmation is logged. You have a direct contact for any issues between service dates.
As your project wraps, we coordinate pickup around your site closeout timeline. No surprise fees for the final week — billing closes on the date we agree.
Commercial clients often come in having gotten a lower number from a competitor. Here's the honest answer on that: the low number usually assumes a servicing frequency that doesn't match the actual crew size, or a response commitment that isn't in writing.
What drives real cost on a commercial rental isn't the daily rate on a single unit. It's the service interruption when a unit hasn't been serviced on schedule and a crew of twenty is standing in front of it. That's a half-day of productivity, a OSHA-adjacent headache, and a conversation with the general contractor you didn't want to have.
Our pricing is built around the servicing model that matches your site. Sometimes that matches the lowest number you've seen. Often it doesn't — but the total operational cost of running a well-serviced site versus a discount one is not a close comparison.
If price is the primary variable, we'll tell you that honestly and point you toward the configuration that fits the budget without compromising the service floor.
OSHA guidelines specify one unit per twenty workers for job sites where workers are on-site for more than three hours. For projects in Knox, PA with crew counts over fifty, we recommend a combination of standard units and at least one ADA-compliant unit. We'll spec the correct count for your file.
Our commercial minimums are typically one week, though month-to-month agreements are the standard for most construction clients. Long-term projects receive tiered pricing that reduces per-unit cost as the project extends.
Yes. If your site layout changes during the project, we can schedule a relocation as part of your service visit or as a standalone trip. Advance notice of two business days is sufficient for most relocation requests.
Yes. Contractors and property managers running multiple active sites in Knox, PA are set up under a single account with consolidated billing and a dedicated contact for scheduling coordination.
Active commercial clients have a direct service line. Same-business-day response is standard for mechanical or service issues. If a unit needs to be swapped rather than serviced on-site, we coordinate a same-day replacement.
We've used three different portable toilet rental companies over the past five years. FMB is the first one that confirmed every service visit in writing. Sounds small until you're trying to verify a service log for an inspection and actually have the documentation ready.
Our crew went from twelve to twenty-eight about halfway through a six-month build. I called FMB expecting to negotiate a new contract. They added units and adjusted the service schedule in one conversation. Billing updated automatically. Exactly how it should work.
Had a compliance issue flagged two weeks before a city walkthrough — our portable setup wasn't ADA-configured for the crew count we'd reported. FMB swapped it out within two days and sent me the spec sheet. Walkthrough went clean. That response alone justified the whole relationship.
